A method for controlling footwear, comprising cushioning a transient force during use of the footwear at a first period of a gait cycle, storing energy from said cushioning, and releasing the stored energy during use of the footwear at a second period of the gait cycle, and after said transient force has subsided. The control can be electronic, mechanical or hydraulic, and is preferably dependent on a sensed gait cycle phase. The control may be adaptive to the user or the use of the footwear. The stored energy can be used to assist in locomotion, to generate electrical energy, to drive a heat pump, or simply dissipated.

A feedthrough terminal assembly for active implantable medical devices includes a structural wire bond pad for a convenient attachment of wires from either the circuitry inside the implantable medical device or wires external to the device. Direct attachment of wire bond pads to terminal pins enables thermal or ultrasonic bonding of lead wires, while shielding the capacitor or other delicate components from the forces applied to the assembly during attachment of the wires.

A method and apparatus for data transmission between an electromedical implant having a first transmitter/receiver unit, such as a cardiological implant, and an associated external apparatus having a second transmitter/receiver unit. Data transmission begins with a triggering signal which is sent by the first transmitter/receiver unit in normal operation in predeterminable first intervals. Reception readiness of the first transmitter/receiver unit is maintained after emission of the triggering signal for a second time interval which is shorter than the first time interval.

An electromagnetic interference filter terminal assembly for active implantable medical devices includes a structural pad in the form of a substrate or attached wire bond pad, for convenient attachment of wires from the circuitry inside the implantable medical device to the capacitor structure via thermal or ultrasonic bonding, soldering or the like while shielding the capacitor from forces applied to the assembly during attachment of the wires.

This invention relates to a polymeric ballistic material comprising a high molecular weight, high density polyethylene (HMW-HDPE) and/or composite, and to articles made from this ballistic material suitable for stopping projectiles. The articles may include backstops for firing ranges and home use, armor for vehicles, personnel, and aircraft, training targets, protection for temporary or mobile military and/or police installations, buildings, bunkers, pipelines or any “critical” need equipment that might require protection from ballistic impact, and the like.

A flexible armor system adaptable to a garment suitable for extremity protection uses planar, polygon-shaped solid elements made of ceramic cores wrapped in high strength fabric and arranged with rotable edge and intersection protection as a flexible mosaic array which is bonded between an elastic strike side spall cover and a high tensile strength flexible backer layer, further supported by a substantial fiber pack. A progressive mode of localized system failure during a ballistic strike includes: a projectile penetrating the spall cover, fracturing the ceramic core of a wrapped SE while being partially deformed; the deformed projectile accelerating the fractured but still wrapped solid element before it so as to free the solid element from the array and drive it through the flexible backer as a combined mass at a reduced velocity into the fiber pack.

A fastener driving apparatus includes a power source, a control circuit, a motor, a first cylinder, a first piston, a linear motion converter, a second cylinder, a second piston, an anvil, a retention element retaining a component of the apparatus, and at least one sensor. During a compression stroke, the first piston compresses gas in a first cylinder to a predetermined pressure. Compressed gas is communicated to the second cylinder and the retention force of the retention element is overcome, to release the retained component of the apparatus, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke of the first piston, a vacuum created in the first cylinder is communicated to the second cylinder, causing the second piston and the anvil to retract to their initial positions.

PCT No. PCT/FR95/01609 Sec. 371 Date Jun. 6, 1997 Sec. 102(e) Date Jun. 6, 1997 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96/18040 PCT Pub. Date Jun. 13, 1996The invention relates to a heterogeneous structure for energy accumulation-dissipation (10), the structure being constituted by a porous capillary solid matrix (11) of open capillary porosity and of controlled topology, with capillary passages (12) of varying section and/or mutually interconnected to form labyrinths, and by a liquid (13) surrounding the porous capillary matrix and defining a liquid/solid separation surface, with the matrix (11) being lyophobic relative to said liquid. The area of the separation surface then varies isothermally and reversibly as a function of the external pressure to which the heterogeneous structure (10) is subjected.

A tank agitator connects to a low head feed and causes agitation by discharging through a port that might rotate, oscillate, or otherwise issue a pulsing stream. This agitator has a housing with a turbine plenum and an exhaust plenum. A turbine in the turbine plenum spins by the flowthrough of the feedwater and exhausts to the exhaust plenum. A hollow drive shaft is spun by the turbine and extends through the exhaust plenum and to terminate outside the housing. It has an aperture that allows water in the exhaust plenum to flow into its lumen. A nozzle caps the shaft and is bent such that the discharge issuing therefrom sweeps in circles with the spinning of the drive shaft. A variant form of the agitator includes a drive train that incorporates a drag link to convert the spinning input of the turbine into an oscillating output in the drive shaft. In another variant form, the discharge is pulsed. To do this, the exhaust plenum lies between an opening to the turbine plenum and a port in the housing wall to the outside. A blocker door is coupled to and driven by the spinning turbine to cycle between uncovering and covering one of the exhaust opening and the discharge port. Given the foregoing, the discharge stream issuing from the discharge port will pulse between alternating phases of flow and quiescence.

An energy dissipative element (24) protects hard disk drives (22, 72, 92) from shocks and vibrations. A closed elastic envelope (48) houses a body of open cell foam (54), a volume of viscous liquid (56), and a compressible gas (64). Under compression or expansion of the foam (54), viscous liquid (56) flows through cell orifices and thereby dissipates energy resulting from external force applied against the elastic wall (48). The energy dissipative elements (24) are applied between a disk drive housing (22) and an outer case (26) to create a ruggedized portable disk drive module (20).

An agricultural machine having a frame carrying a crop pickup mechanism and supported on the ground by means of two support wheels. Each support wheel is rotatably mounted on a carrier that is connected to the frame of the pickup for rotation about a caster axis. Each wheel carrier is connected by a respective spring to a point fixed relative to the frame of the pickup. The spring biases the carrier to cause the support wheel to park in a predetermined direction relative to the frame of the pickup.

Among others, the invention relates to a method and a system for controlling a system for receiving a wireless data transmission between at least two components (12, 100, 50), wherein at least one wireless interface (102, 112) can be activated, or is activated, for wireless data transmission. According to the invention, a first component (100) monitors an environment for the occurrence of at least one predefined change and/or for the occurrence of at least one predefined feedback from the environment. Once such a change, or feedback, has occurred, a wireless interface (102) is activated for the wireless data transmission, and optionally for the energy supply of a second component (50) via the wireless interface. The predefined change or feedback is caused particularly in that the second component (50) is returned to the environment. The system may be a system (10) for determining the identity and/or authorization, such as a locking system. The first component (100) may arrange an interaction between the second component (50) and a further component (12), which, for example, is associated with a target mechanism.
